The CMT Music Awards are often noted for their irreverence, and sometimes for the shock value of pairing country performers with acts from outside the format. While this years' telecast had plenty of those moments this year -- with appearances from Nelly and Lenny Kravitz, there was also a great deal of emotion on the show.

Taking to the stage late in the program, Big Machine's Rascal Flatts brought up the recent devastation due to the tornados in Oklahoma. Member Joe Don Rooney introduced his fellow Okie, Carrie Underwood, to the stage. The Arista superstar responded with the emotional musical centerpiece of the night with a performance of her current single "See You Again."

Performing in front of a video backdrop of the devastation from the recent tornados, Underwood delivered what might have been one of her greatest live performances yet. The Grand Ole Opry star performed while being backed by a choir from Nashville's Christ Church. The song was dedicated in memory of those who lost their lives in the deadly tornados that swept through Moore on May 20. 

Underwood made news recently by donating $1 million of the  proceeds from her recent "Blown Away" tour to the American Red Cross to help aid victims of the tornados. 

With a long history of country music performers, Underwood's fellow Okies have also stepped in to help with aid efforts. Blake Shelton, Reba McEntire, and Vince Gill all united their talents last Wednesday (May 29) for the "Healing In The Heartland" concert in Oklahoma City which also included performances from Luke Bryan, Darius Rucker, and Rascal Flatts -- with other artists also planning as-yet-to-be-announced benefits.
